zz Claims'. (o1. 229-29) This invention relates to collapsible cardboard boxes or containers and more particularly to the type, in which eggs are shipped, stored and sold by the retail trade.

V5 It is an object of this invention to p-roVi-de an egg box having a pair of collapsible blanks forming the body of the box, and partitions made of one strip of cardboard, folded in such a way as to permit the partition to swing when the box is in collapsed position.

It is another object of this invention to provide a container having two collapsible sides and a folded filler strip, the inner portions of the side members being locked to the ller strip such Aas to give a substantial rigid box construction.

It is another object of this invention to provide a collapsible egg box with a fol-ded filler strip, the Wall portions of which filler strip are Secured to the sides of the box by cementing or stapling.

2O It is a further object of this invention to provide a container having two blanks forming the body of the container and partitions swingably connected to the blanks whereby the blanks are .movable relatively longitudinally and towards 25 each other.

This invention accordingly consists in the features of construction, combination of parts and 4in the unique relations of the members and in the relative proportioning and disposition there- 30 of all as more completely outlined herein.

To enable others skilled in the art so fully tol comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated byV this invention, drawings depicting cer.-A tain forms of the invention have been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views, of which:-

Fig. 8 is a plan View of a modified form of the invention, the container being in the collapsed positionfready for assembly. Fig. 9 is a bottom View of Fig. 8, the front portion however having been drawn out in the rst step in assembling.

. Fig. 10 is a perspective view of the container fully assembled, the cover being partly open.

Fig. 11 is a side elevational view of Fig. 10 with the cover closed.

The 4rear portion of the outer casing or body is formed of one blank I0, the front portion of the louter casing or body is formed of another blank I I and the center filler is formed of a single blank l2. The rear portion I has attached to it the ,coverportion 'I3 with a closing strip I4. L represents fold lines (along which the various portions are folded. Portion I represents the .straight lrear wall. I6 is the inclined rear wall and I.,'Iv is the inclined front Wall of the rear portion..` The straight upright wall I8 of the rear 25 andthe wall .portions 26. The Wall portions 26 areglued, cemented or stapled, or otherwise secured to the wall portions I5 and 2U. The zigzag waypf folding the filler strip is clearly illustrated.inF-ig. 5, .the place of fastening being at 2'I, 28, 29, 30, 3l, 32, 33 and 34. The filler portions are provided with extensions and 36, which pass through openings 39 and 40 in walls Iliand 2l, respectively. Walls I8 and 23 are held in place byl the slot 31 in thei'illers and are locked byhaving therlugs 4I and 42 of the cutouts I9, 24, respectively, pass through the openings 38 in the filler.. Slots 43 in the ller strip are provided to receive the closing strip I4. VThis closing strip I4 is provided with notches 44 which engage with the portions 250i the filler strip I2.

rv.Inthe modication shown in Fig. 7, the spacer 25has a straight portion 45 which passes through s1o`t's1in'th'e-bottom portions I I and 22'. The lugs 35" and 36 :pass through the openings 39' and 40' f portions =I6f and 2 I To"assemble the device, the blank I0`is placed,

say on a table and the iiller strip I2 in its folded condition is attached to wall I5 by any suitable means, at the points 21, 29, 3| and 33.

Blank is then placed over the folded ller strip and secured thereto at the points 28, 30, 32 and 34. In this construction the body portions of the box are built upon the ller strip I2, which differs radically from the conventional manner of building the ller strips or partitions upon the body of the box. The box is now ready for storing or shipping. To fold the container into position ready for use, all that is required is to swing the blank forwardly, which when the box is positioned as in Fig. 4, will be to' the left, until the spacers 25 are at right angles to the blanks |0 and The spacers 25 act as swinging arms. Then the center or locking upright walls |8 and 23 of the blanks I and I I are locked in the position as clearly illustrated in Fig. 6.

In the embodiment of the invention, shown in Y Figs. 8-11, inclusive, the container consists of three parts, the rear wall portion 15, the filler portion 16 and the front portion 11. 'I'he rear portion 'I5 consists of the rear wall portion 18, the cover portion 19 and the closing strip 80. 'Ihe filler portion 16 consists of the partitions 84 swingably attached to the portions 15, 16, which may be, for example, by means of the end strips 8| and 82 and the intermediate strip 83 cemented or otherwise secured to the respective wall sections.

The front .portion 11 consists of the outside front wall 85 the inside front wall 86, the two inclined, front bottom portions 81 and 88, the two center partition portions 89 and 90, the two inclined rear bottom portions 9| and 92 and the rear wall portion 93. Portions 86 to 93 inclusive are provided with slots 94 and 95, respectively, which permit in the assembling for the bottom portion of the center spacers 84 to pass through.

The container is assembled very easily and readily. The collapsed blank as shown in Fig. 8 has the iront portion 11 moved out into the position shown in Fig. 9, and the portions 86 to 93 inclusive are folded inwardly and downwardly along the fold lines 9s, 91, 9a, 99, then through the center partition fold line |00 and again through fold lines IUI, |02 and |03. The cover portion 19 folds along fold lines |08 and |09.

Notches |04, and |06 will ho'ld'the folded portions in their respective places. The closing strip 80 is provided with notches |01 for keeping the cover in the closed position as shown in Fig. 11. This embodiment of the invention shows a container for 6 eggs only, but the construction can be made for any number of eggs by lengthening the box similar to that illustrated in Fig. 6. v

It is believed from the above description that those skilled in the art willy have no difliculty in understanding the construction, the method of use and operation of the device herein disclosed and a detailed discussion thereof is unnecessary. The invention is of simple and practical construction and is adapted to accomplish among others all of the objects and advantages herein set forth.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features, that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
